great focusing aid for refractors

this is a must for accurate focusing on stars. live view helps, but the bathinov mask will get you in sharp focus every time.

Farpoint FP401 Bahtinov mask

Needed a focusing mask for my WO 110 ED for DSLR imaging. This product worked perfectly, and the price shipped was a pleasant surprise. Highly recommended!

Essential! It will pay for itself fast!

I remember one night I spent four hours trying to get a great photo of a nebula. Through the camera viewfinder it looked like everything was in sharp focus. After coming back inside it turns out that the camera slid slightly in the focuser. It slid just enough to render about 3 hours of time totally wasted! The Farpoint Bahtinov mask is a great way to check your focus and check to make sure your camera did not slip. The time you save will make it well worth the cost. HIGHLY recommended!

Must have for photography!

I use this on an astro-tech 6" Ritchey-Chretien and an astro tech 6" imaging newtonian. This makes it easy (and the cheapest of all the possible ways) to achieve tack-sharp focus.
